Now that the Mozart celebrations have really begun, our classical music listening opportunities are going to multiply out of control. Hang on tight, dear readers, because February is going to be busy. We will be here every Sunday to offer some guidance. As always, if you want the whole story, head over to our Classical Week in Washington feature at Ionarts.

FREE CONCERTS:
>> All of the regular free concert series in Washington are now back from their winter breaks. This week, the Library of Congress begins hosting concerts again. On Thursday (February 2, 8 p.m.), there is a concert dedicated to the chamber music of Roger Reynolds, an eclectic composer who won the Pulitzer Prize in 1989 and combines traditional sounds with electronic and computer ones. Reynolds has a special relationship with the Library of Congress, which holds a special collection of the composer’s personal papers and other materials. His opera, Justice, on the story of Clytemnestra and Agamemnon, was commissioned for the Library’s anniversary in 2000, and it was designed specifically for the space where it was premiered, the Great Hall of the Thomas Jefferson Building. Then on Friday (February 3, 8 p.m.) the Cuarteto Casals will play string quartets by Arriaga, Mozart, and Zemlinsky.

>> At the museum concert series, there are free concerts on Sunday (February 5, 5 p.m.) by the piano, clarinet, and violin combination of the Verdehr Trio at the Phillips Collection. Later that evening (February 5, 6:30 p.m.), the Mozart Piano Quartet will play an all-Mozart program, in conjunction with the Mozart on the Mall concert series, at the National Gallery of Art.
